Mixing copper and zinc atoms produces the alloy brass. What would be produced with the fusion of copper and zinc nuclei?

atomic number Cu + atomic number Zn = atomic number of X.

mass number of Cu + mass number of Zn = mass number of X (before splitting if it splits).

The fusion of copper and zinc nuclei would result in the creation of a different element through nuclear reactions. Fusion occurs when atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy in the process. In the case of copper and zinc, fusion reactions are not common because they are not elements that typically undergo fusion reactions under normal circumstances.

However, hypothetically, if copper and zinc nuclei were brought together under extreme conditions of high temperature and pressure, fusion could occur. Fusion reactions involving copper and zinc nuclei would undergo a complex series of nuclear reactions, leading to the production of different elements. Depending on the specific conditions and reaction pathways, various elements could be formed, including those with higher atomic numbers.

It's important to note that such fusion reactions between copper and zinc nuclei would require highly specialized equipment and conditions that are far beyond the capabilities of current technology. Additionally, fusion reactions involving copper and zinc have not been observed in nature.

To summarize, while the fusion of copper and zinc nuclei could potentially produce different elements, this type of fusion reaction is not observed in normal conditions and would require extreme circumstances not currently achievable with existing technology.
